Abstract
The main body of the nozzle (5) includes a core (10) surrounded by a tubular casing (11). Nozzle tip (12) and (lower) resting surface are solidly-connected to the core. The core is axially- and resiliently-compressible. It is guided in limited axial movement by the casing. Preferred features: The cooling channel is a space bordered by the core and casing, and takes the form of a circumferential spiral groove (14) in the core. Core and casing are connected near the tip; at the other end they are sealed for relative axial sliding. Here too, there is a ring seal (16) acting against a bore into which the nozzle assembly is inserted. The (upper) resting surface (13) is an end face of the core. Cooling channels constitute roughly 55% of the cross sectional area of the core. An Independent claim is also included for a corresponding injection mold. A bore in the mold assembly houses the nozzle described, which is thermally-insulated from the mold.
